Milling spindle motor adopts a non-housing structure, the stator silicon steel sheet is directly cooled by air, which can work safely and reliably in the case of dust and cutting fluid splashing. The milling spindle motor usually does not need maintenance, because the AC spindle motor has no commutator in the structure. The addition of spindle subsets is not restricted by commutators, and the maximum speed is usually higher than that of dc spindle subsets. The cooling air of the spindle motor flows from the front to the back, which can effectively reduce the influence of motor heating on machine accuracy. In the cooling system, in order to reduce volume and improve efficiency, FANUC spindle motor uses a special enterprise heat pipe cooling system, which can quickly dissipate the heat generated by the rotor outside.
